- Black, with a background in open source and cybersecurity, currently works at CISA, which coordinates U.S. cyber defense and focuses on creating a sustainable OSS ecosystem.
- Key initiatives discussed included improving vulnerability disclosure processes, promoting memory-safe programming languages like Rust, and the Software Bill of Materials (SBOM) for software supply chain transparency.
- The event underscored the need for collaboration and community involvement to address contemporary challenges in OSS, particularly in light of advancements in artificial intelligence.
Aeva Black Delivers Keynote at RustConf 2024
Aeva Black delivered the opening keynote at RustConf 2024, held in Montreal, Canada, and online. The conference, hosted by the Rust Foundation, is designed to foster discussions about the Rust programming language and its community.
The Role of Open Source Software
This year’s event brought attention to the crucial role of open source software (OSS) in various sectors, including critical infrastructure and the U.S. government. The conference emphasized the need for enhancing the security of OSS by design and by default.
Black has a rich background in open source, cloud automation, and kernel maintenance. They commenced their career as a hacker in the 1990s and have experience in gaming startups, contributing to Debian kernel maintenance. Currently, Black works at the Cybersecurity and Infrastructure Security Agency (CISA) in the U.S., where they were invited by the White House due to their expertise in open source and cybersecurity. CISA is the primary agency for cyber defense in the U.S., coordinating efforts related to critical infrastructure security and aiming to reduce risks across sectors such as power, water, healthcare, and transportation.
Economic Impact and Security Challenges
The keynote highlighted the significant economic impact of open source software, which contributes an estimated $8 trillion annually. However, only $4 billion is reinvested into its development, indicating a substantial funding imbalance. A small percentage of core OSS maintainers—only 5%—are responsible for producing 96% of the value in open source contributions.
The discussion addressed prevalent memory safety issues, such as buffer overflows, which are major contributors to vulnerabilities in OSS. The principle known as Linus’ Law, which posits that “many eyes make bugs shallow,” was described as outdated due to the growing volume of code in modern software.
Black discussed the historical context of open source, tracing its origins back to 1990s court rulings that recognized source code as protected creative work. Organizations like the Free Software Foundation (FSF) and the Open Source Initiative (OSI) have established frameworks that define OSS principles.
CISA’s Roadmap and Future Directions
CISA’s roadmap for open source focuses on creating a sustainable, secure, and resilient OSS ecosystem. Key initiatives aim at coordinating open source efforts across federal agencies and engaging with OSS communities. Projects under CISA’s roadmap include improving vulnerability disclosure processes and advocating for memory-safe programming languages like Rust.
The Software Bill of Materials (SBOM) initiative is particularly noteworthy, aiming to enhance transparency and security in the software supply chain by creating detailed dependency graphs that can help identify vulnerabilities. CISA is actively involved in incident response stress-testing alongside the Rust community and is promoting a 10-year memory-safety roadmap for organizations.
The focus of open source development on collaboration, transparency, and trust is seen as essential for addressing contemporary challenges, including those posed by artificial intelligence (AI). Community involvement is encouraged to secure the future of open source, with strategies proposed for making open source inherently secure, promoting memory-safe programming languages, and enhancing review processes.
The discussions at RustConf 2024 underscored the necessity of developing sustainable ecosystems that support core maintainers and critical projects within the open source landscape, ensuring that security considerations adapt to advancements in the field.
